Oh, write away! Conversions are in many ways much harder because, as you note, the thing is designed for looks and not to fit all the stuff inside that a full RC needs.
Heck, the only conversion I've done is from a vintage wired RC to modern wireless (admittedly with some other work), and getting the battery and whatnot to fit was a nightmare. I've gotten spoiled doing scratch builds and adjusting the shape or dimensions as required to get the desired components to work.
Also, as obvi you're aware, forks are bloody complicated. I did one and while it works well enough, the scale and appearance suffer a bit for that.
Finally, this one looks like the tines are adjustable-spacing, which was a luxury I couldn't squeeze into mine. I had to have fixed-spacing tines on a carriage that shifted side-to-side. I'd love to see how you made all the moving parts ... well, move
